. FURNACE-CHARGING APPARATUS.

Original No. 1,012,235, dated December 19, 1911, Serial No. 630,966, led .Tune 2, 1911. Application for reissue filed November 19, 1921.

To all whom t may'wncern:

Be it known that 1, SARL E. BEDELL, a citizen of the United States of America, and resident of lVheeling, county of Ohio, and

State of Test Virginia, have invented cer-A I whereby a powerful thrust may be given the material for directing the latter comparatively ng distances, and whose throw may be regulated for depositing the material at desired points by simply increasing or reducing the speed of a motor or other power mechanism employed for driving.

Another object withinthe contemplation of the invention is to provide in a charg` ing apparatus a revolving magnetic wheel whereby the metal is seized and delivered or directed forward into the. furnace.

With these and other important objects in view, the invention finally consists in the features of construction, arrangement of parts and cfnnbinations of elements which will ln-reina fter be exemplilied, reference being had to the aceomlmnying drawings, forming a pn rt ol' this sluwifit-ation, in Whichv Figure l is a side elevation of the invention, the elevating mecl'ianism being shown in inoperative position.

Figure 2 is atop plan View ol' the same.

Figure 3 is a view similar toi Figure 1., showing the parts of the invention in normal operative position.

Fi 'ure 4 is a cross section on [he linel l-4 of Figure 1.

Figure 5 is an enlarged detail view, partly in section, of the magnetic wheel.

,Referring to said drawings, in which Vlike designating characters distinguish 4like parts serial No. 516,487;

throughout the seveial views,1 indicates a'loading table or bench Which has a plurality of supports 2 mounted on its top for supporting the pile 3 of plates, skelp, or other material, to be charged into the heating furnace et, said table being located in front of the mouth or door 5 of the furnace, and being, preferably, mounted upon wheels 6 and arranged to travel along, trackrails 7 across the front of the furnace, whereby the machine may be adjusted to any desired position with respect to the latter. Mounted upon the front end of the table and located laterally of the position occupied by the pile 3 of material to be charged, is the upright member of an angular supporting frame 8 which has a member 8a in overhanging relation to said pile. Brackets 9 are mountedon the rear face of the frame member 8. `Said brackets are either niagnetically isolated from the frame, or are made of brass or other non-magnetic material. Journale-d in said brackets so as to lie transversely of the table, is a shaft. 1() upon which is lixed a magnetic wheel, designated generally by the numeral 11. Said wheel comprises a pai of circular disks 12 having portions of thiiir opposing faces in engagement, substantially as shown in Fig. 5. Provided in the. adjacent faces of said disks are oppositely facing circular grooves or channels 13, concentric with said disks, in which is mounted a circular magnet coil 14, insulated from said disks, to which leads a pairof current-conducting wires 15, the latter being herein shown as leadin throu h or along a channel 'provided there or in t e shaft l() and in one of the disks 12. Slip rin gs IG mounted on and insulated from said .shaft have brushes 1T, to which lead wires 18, in contact therewith.. An annular airspace, l!) is provided between the coil 14 and the I )criphery of the wheel 1l, aid a shield, or protecting ring 20, of non-magnetic material is shown disposed across said airspace and mounted in the opposing disk llangcs 12".

'lhe centers or engagin body portions of the disks V1.2 and the sha t 10together `constitute a core for the magnet, and the separated peripheral flanges 12* of the disks constitute the poles of the magnet. Magnetism is communicated from the magnet wheel 11 across narrow intervening air-gaps to a pair of arms 21. Said arms are located on opposite sides of wheel 11 and each has one end loosely mounted on a boss 9"' carried by the adjacent bracket 9. Magnetism .1s thence transmitted to a pair of arms 22 the magnetized arms 22, the lifting power vmagnetic wheel 1l, any

of said rollers will be strengthened or weakened respectivelyV as the air gap between rollers 23 and their respective arms 22 is diminished or increased.

While the construction or arrangement above described for varying the strength or lifting power of the rollers is deemed preferable, it is obvious that other strength varying`means may be employed, it' desired.

he weight of the arms 21 and 22 and rollers 23 normally maintains the latter in engagement with the topmost piece of skelp in the pile 3; hence, magnetism is communicated to the said topmost piece and, when said rollers are elevated, the front end of said piece is elevated. therewith.

The wheel 11 is driven at a rapid rate of speed, any preferred form Aof gearing or driving mec anism being employed. The gearing herein shown comprises a horizontal drive shaft 24 having bevel gear connection, as shown at 25, with a vertical shaft 26 which is, in turn, connected hy bevel gears, as shown at 28. to shaft l0.

For elevating the rollers 23 to effect the raising of the ront end ot a pieve of skelp into engagement with the periphery ol' theI appropriate means may be employed, that herein shown being at present/preferred on account of its siniplicity, and consisting of a crank arm 2T fixed to, or formed integralwith, one of the arms 21, giving the latter substantially bell crank form, and an operating lever 29 pivotally connected to thevlower, or free, end of said arm 27. As is obvious, a rearwardly directed pull upon the lever 29 effects the.

elevation of arms 2l and 22 and of rollers 23, as shown in full lines invFig. 1 and in 'dotted lines in Fig. The piece of metal is elevated from the table with the rollers 23 and is thus carried into contact with the periphery of the rapidly rotating wheel 11, as shown in Fig. 3 wherein in full lines the device is shown in the act of pickin up the last sheet of the pile. Being elevate against said wheel, the plate 'is seized thereby, owi

ing to the magnetism of the wheel, and is carried forward over' the furnace apron 3'1 and through the o en mouth or door 5 into the furnace, as's own in dotted lines iu Fig. 3. vThe force of the thrust and, consequently, theA distance over which the metal piece is projected into the furnace is de- It will be obvious that various changes.

in the construction and arrangement of parts composin" the machine may be resorted to without eparting from the general spirit or scope of the invention as defined in the ap ended claims.
